Binglan Yu, PhD

Binglan Yu researches blood transfusion and blood substitutes with the goal of making transfusion of human blood stored for prolonged periods a safer clinical process.

Instructor of Anesthesia, Harvard Medical School
Research Areas

  • To elucidate the mechanisms by which transfusing stored red blood cells (RBCs) inducing adverse effects (e.g. vasomotor, inflammatory, and platelet activating responses)
  • To develop in vitro and in vivo methods to reduce the adverse effects to infusion of RBCs stored for prolonged periods  
  • To evaluate the efficacy and safety of transfusing blood substitutes (hemoglobin-based oxygen carriers)

Description of ResearchMy research interest has been focused on blood transfusion and blood substitutes. We have developed two animal models of blood storage, one in the mouse and one in the sheep. We have characterized the storage models in vitro and in vivo. Most recently, we have studied of transfusion fresh RBCs and stored RBCs to resuscitate mice and sheep from hemorrhagic shock. We have been working on selectively oxidizing the supernatant oxy-hemoglobin of stored RBCs to met-hemoglobin, and, thereby, preventing the adverse responses to stored RBC transfusion. My goal is to make transfusion of human blood stored for prolonged periods a safer clinical process.
